I've just had an AV80R delivered from Harry's and having a play so far on the ground (as the wx won't let me use it in anger), it seems to be the business for a no-nonsense GPS.
The touchscreen is great - you can drag the map around, tap on airspace, obstacles, airfields etc and get more info, MATZ & VRPs all seem to be there (for my local area anyway), and the topo map/profile view looks pretty handy. The update on the website adds extended runway centerlines, and a few other goodies.
Works great as a Car satnav too. Also plays movies/sound/ebooks (although what use that'll be I dunno, except for occupying the nipper on a long car drive).
Standard USB connection, and SD card for storage. Charges off the USB port too, which is nice.
Battery life with the standard battery is about 1.5 hours which is a bit low, but standard nokia battery so easy and cheap to get a bigger one.
Comes with suction mount, yoke mount, usb cable, headphones, AC adapter (UK & Euro pins).
Registered on the Bendix site a few hours back and got my maps update confirmation through - aside from that £35 for an update (or you can get a sub).
Went for the AV80R in preference to the Clarity - CAA charts aren't vector so they pixelate when zooming, no usb/standard port, no car nav (not a biggy but nice to have), no on-map topo.
So far so good. Hoping to head to the St Omer fly in around the 12, so will be comparing it with a 296 and 250XL which are coming too.
